Compounds of the present invention can be made as shown in the following schemes, in which, unless otherwise stated, the definition of each variable is as defined above for a compound of formula (I).

The process according to the invention for preparing compounds of formula (I) is carried out by methods known to those skilled in the art, and described in more detail below. For example, compounds of formula (I) can be prepared by reaction of a carboxylic acid of formula (II):

wherein R¹, R², R³, A and R⁵ are as defined under formula (I), with an amine of formula (III):

wherein R⁴ is as defined under formula (I), under various conditions well known to those skilled in the art, some of which are outlined in Scheme 1.

As shown in Scheme 1 compounds of formula (II), wherein R¹, R², R³, A and R⁵ are as defined in formula (I), are activated to compounds of formula (IIa) by methods known to those skilled in the art and described for example in Tetrahedron, 61 (46), 10827-10852, 2005. For example, compounds of formula IIa where X₀ is halogen are formed by treatment of compounds of formula (II) with for example, oxalyl chloride or thionyl chloride in the presence of catalytic quantities of DMF in inert solvents such as methylene dichloride or THE at temperatures between 25-170° C., preferably 25-80° C. Treatment of (IIa) with compounds of formula (III), wherein R⁴ is as defined in formula (I), optionally in the presence of a base, e.g. triethylamine or pyridine leads to compounds of formula (I). Alternatively, compounds of formula (I) can be prepared by treatment of compounds of formula (II) with dicyclohexyl carbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) to give the activated species (IIa), wherein X₀ is X₀₁ or X₀₂, in an inert solvent, e.g. pyridine, or THE optionally in the presence of a base, e.g. triethylamine, at temperatures between 50-180° C. In addition, an acid of the formula (II) can also be activated by reaction with a coupling reagent such as propanephosphonic acid anhydride (T3P®) or O-(7-Aza-1-benzotriazolyl)-N,N,N′,N′-tetramethyluronium-hexafluorophosphat (HATU) to provide compounds of formula IIa wherein X₀ is X₀₃ and X₀₄ as described for example in Synthesis 2013, 45, 1569 and Journal Prakt. Chemie 1998, 340, 581. Subsequent reaction with an amine of the formula (III) provides compounds of formula (I).

Intermediates of Formula (II):

wherein R¹, R², and R⁵ are as defined in formula (I), can be prepared from compounds of formula (IV):

wherein R¹, R², R³ and R⁵ are as described in formula (I), and R¹⁰ is C₁-C₆alkyl, by acid or base hydrolysis. For example, compounds of formula (IV) wherein R¹⁰ is t-butyl, upon treatment with mineral acids or trifluoro acetic acid in an inert solvent such as methylene chloride or dioxane leads to compounds of formula (II). Alternatively, base hydrolysis of compounds of formula (IV), wherein R¹⁰ is for example methyl, ethyl, isopropyl and the like, with aqueous alkaline earth metal bases such as lithium, sodium or potassium hydroxides optionally in the presence of a water miscible solvent such as THF, dioxane, acetone and the like leads to compounds of formula (II). Such reactions are well known to those skilled in the art. Compounds of formula (IV) can be prepared by reaction of compounds of formula (V):

wherein R², R³, R¹⁰ and A are as previously described, and Xa¹ chlorine, bromine, iodine, arysulfonate, alkylsulfonate or trifluoromethanesulfonate, with compounds of formula (VI):

wherein R⁵ is as defined as in formula (I), under Buchwald-Hartwig coupling conditions. The Buchwald-Hartwig reaction is well known to those skilled in the art, and is a chemical reaction used in organic chemistry for the synthesis of carbon-nitrogen bonds via the palladium-catalyzed coupling reactions of amines with aryl and heteroaryl halides and sulphonates. Such reactions have been reported in, for example, ACS catal., 2019, 3822-3830 and references cited therein. The reaction typically involves a palladium catalyst such Pd(OAc)₂, Pd₂(dba)₃, and ligands such as diphenylphosphinobinapthyl (BINAP), diphenylphosphinoferrocene (DPPF), and Xathphos. More modern methods of Buchwald-Hartwig couplings involve the use of palladium pre-catalysts such as BrettPhos Pd G3 (CAS[1470372-59-8]) or RuPhos Pd G3 (CAS [1445085-77-7]), use of which ensures the efficient and rapid generation of the active catalytic species. The reaction requires presence of bases such as alkaline earth metal alkoxides and hydroxides, for example potassium or sodium t-butoxides or hydroxides, alkaline earth metal carbonates such as sodium or cesium carbonates, and organic bases such as 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU). The reactions are carried out in a variety of inert solvents such as THF, water, toluene, dioxane, and DMF and/or mixtures thereof at temperatures between 20-170° C. (Buchwald, S. L. Chem. Rev., 2016. 116(19), 12564). The reaction is especially favored in cases wherein R¹ is hydrogen.

The chemistry for the synthesis of compounds of formula (I) is summarized in Scheme 2.

Those skilled in the art will recognize that the order of the reactions can be changed and compounds of formula (I) can also be synthesized as shown in Scheme 3

As shown in Scheme 3, esters of formula (V) can be hydrolyzed to compounds of formula (Va) by methods previously discussed and known to those skilled in the art. Acids of formula (Va) can be activated to compounds of formula (Vb), wherein X₀ is halogen or X₀₁, X₀₂, X₀₃ or X₀₄ as previously defined, also using methods previously discussed, which upon treatment with compounds of formula (III) under the conditions discussed in Scheme 2, lead to compounds of formula (VII). Previously discussed Buchwald-Hartwig amination of compounds of formula (VII) with compounds of formula (VI) leads to compounds of formula (I).

A further synthesis of compounds of formula (I) is shown in Scheme 4:

As in Scheme 4, compounds of formula (Vc), wherein A, R¹, R² and Xa¹ are as previously described and R³ is hydroxy, are converted to compounds of formula (VIIa) using Buchwald-Hartwig chemistry previously described. Compounds of formula (VIIa) thus obtained have their carboxyl group activated by previously described methods to give compounds of formula (VIIb), which upon treatment with compounds of formula (III) also as previously described, leads to compounds of formula (Ia). Compounds of formula Ia can be converted to compounds of formula Ib by an alkylation reaction, well known to those skilled in the art. For example, reaction of compounds of formula Ia with a compound of formula R¹¹—Xa², wherein R¹¹ is C₁-C₆alkyl, C₁-C₆haloalkyl, C₃-C₆cycloalkyl, C₃-C₆halocycloalkyl, C₂-C₆alkenyl, C₂-C₆haloalkenyl, C₂-C₆alkynyl, C₂-C₆haloalkynyl, C₁-C₆cyanoalkyl, C₁-C₆alkoxyC₁-C₃alkyl-, C₃-C₆cycloalkylC₁-C₂alkyl-, oxetan-3-yl, or oxetan-3-yl-CH₂—, and Xa² is halogen, in the presence of a base, such as cesium, sodium or potassium carbonate, and an inert solvent, such as DMF or acetonitrile leads to compounds of formula Ib. Compounds of formula Ia can also be prepared from compounds of formula (Ib), wherein R¹¹ is methyl, by treatment with pyridinium hydrochloride optionally in the presence of a solvent at temperatures between 50-170° C., either in the melt of the presence of a solvent. This is shown in Scheme 5.

Compounds of formula (I) wherein R¹ is cyano, C₁-C₆alkylcarbonyl, and C₁-C₆alkoxycarbonyl can be prepared by methods well known to those skilled in the art. For example, compounds wherein R¹ is C₁-C₆alkylcarbonyl and C₁-C₆alkoxycarbonyl can be obtained as shown in Scheme 6.

As shown in Scheme 6, compounds of formula (VIII), wherein R^(1a) is C₁-C₆alkyl or C₁-C₆alkoxy can be activated to compounds of formula (VIIIa) by methods shown in Scheme 2 and as discussed previously in Scheme 1. Subsequent reaction of compounds of formula (VIIIa) or (VIII) with compounds of formula (Ic), optionally in the presence of a base, leads to compounds of formula (Id).

Compounds of formula (I), wherein R², R³, R⁴, and A are as defined for formula (I), and R¹ is cyano, namely compounds of formula (Ie), can be obtained by reaction of a compound of formula (IX), wherein Xa³ is halogen, preferably bromo, either by thermal heating, or with the aid of a base, such as sodium hydride, butyl lithium, or an organic base such as pyridine, in an inert solvent such as THF, dioxane, methylene chloride and the like with compounds of formula (Ic). This is shown in Scheme 7.

Similar reactions have been reported in the literature, for example Eu. J. Chem., 24(52), 13788-13791, 2018, Org. Lett., 19(14), 3835-3838, 2017, and Synthesis, 3077-3088, 2009.

Compounds of formula (III), (VI), (V) and (VIII) are either commercially available or known in the literature.

Surprisingly, it has now been found that the novel compounds of formula (I) have, for practical purposes, a very advantageous level of biological activity for protecting plants against diseases that are caused by fungi.

The compounds of formula (I) can be used in the agricultural sector and related fields of use, e.g., as active ingredients for controlling plant pests or on non-living materials for control of spoilage microorganisms or organisms potentially harmful to man. The novel compounds are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and may be used for protecting numerous cultivated plants. The compounds of formula (I) can be used to inhibit or destroy the pests that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later, e.g., from phytopathogenic microorganisms.

The present invention further relates to a method for controlling or preventing infestation of plants or plant propagation material and/or harvested food crops susceptible to microbial attack by treating plants or plant propagation material and/or harvested food crops wherein an effective amount a compound of formula (I) is applied to the plants, to parts thereof or the locus thereof.

It is also possible to use the compounds of formula (I) as fungicide. The term “fungicide” as used herein means a compound that controls, modifies, or prevents the growth of fungi. The term “fungicidally effective amount” means the quantity of such a compound or combination of such compounds that is capable of producing an effect on the growth of fungi. Controlling or modifying effects include all deviation from natural development, such as killing, retardation and the like, and prevention includes barrier or other defensive formation in or on a plant to prevent fungal infection.

It is also possible to use compounds of formula (I) as dressing agents for the treatment of plant propagation material, e.g., seed, such as fruits, tubers or grains, or plant cuttings (e.g., rice), for the protection against fungal infections, as well as against phytopathogenic fungi occurring in the soil. The propagation material can be treated with a composition comprising a compound of formula (I) before planting: seed, e.g., can be dressed before being sown.

The active ingredients according to the invention can also be applied to grains (coating), either by impregnating the seeds in a liquid formulation or by coating them with a solid formulation. The composition can also be applied to the planting site when the propagation material is being planted, e.g., to the seed furrow during sowing. The invention relates also to such methods of treating plant propagation material and to the plant propagation material so treated.

Furthermore, the compounds according to present invention can be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage, in hygiene management.

In addition, the invention could be used to protect non-living materials from fungal attack, e.g., lumber, wall boards and paint.

An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding (mutagenesis) is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides or classes of herbicides by genetic engineering methods include glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.

The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.

Examples of such plants are: YieldGard® (maize variety that expresses a Cry(IA)(b) toxin); YieldGard Rootworm® (maize variety that expresses a CryIIIB(b1) toxin); YieldGard Plus® (maize variety that expresses a Cry(IA)(b) and a CryIIIB(b1) toxin); Starlink® (maize variety that expresses a Cry9(c) toxin); Herculex I® (maize variety that expresses a CryIF(a2) toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry(IA)(c) toxin); Bollgard I® (cotton variety that expresses a Cry(IA)(c) toxin); Bollgard II® (cotton variety that expresses a Cry(IA)(c) and a CryI(IA)(b) toxin); VIPCOT® (cotton variety that expresses a VIP toxin); NewLeaf® (potato variety that expresses a CryII(IA) toxin); NatureGard® Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait), Agrisure® RW (corn rootworm trait) and Protecta®.

The term “crops” is to be understood as including also crop plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.

Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins from Bacillus cereus or Bacillus popilliae; or insecticidal proteins from Bacillus thuringiensis, such as δ-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases.

In the context of the present invention there are to be understood by δ-endotoxins, for example Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for example Vip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G-recognition sequence is inserted into a Cry3A toxin (see WO 03/018810).

Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073. The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0 367 474, EP-A-0 401 979 and WO 90/13651.

The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera).

Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGard Rootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGard Plus® (maize variety that expresses a Cry1Ab and a Cry3Bb1 toxin); Starlink® (maize variety that expresses a Cry9C toxin); Herculex I® (maize variety that expresses a Cry1 Fa2 toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses a Cry1Ac toxin); Bollgard II® (cotton variety that expresses a Cry1Ac and a Cry2Ab toxin); VipCot® (cotton variety that expresses a Vip3A and a Cry1Ab toxin); NewLeaf® (potato variety that expresses a Cry3A toxin); NatureGard®, Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

Thus, in a preferred embodiment, the compounds of Formula (I) (including any one of compounds described in Table 3 (below)), or fungicidal compositions according to the present invention comprising a compound of Formula (I), are used to control fungal strains which are resistant to one or more fungicides from any of the following fungicidal MoA classes: quinone-outside-inhibitors (QoI), quinone-inside-inhibitors (QiI), succinate dehydrogenase inhibitors (SDHI) and sterol demethylation-inhibitors (DMI).

The term “locus” as used herein means fields in or on which plants are growing, or where seeds of cultivated plants are sown, or where seed will be placed into the soil. It includes soil, seeds, and seedlings, as well as established vegetation.

The term “plants” refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, foliage, and fruits.

The term “plant propagation material” is understood to denote generative parts of the plant, such as seeds, which can be used for the multiplication of the latter, and vegetative material, such as cuttings or tubers, for example potatoes. There may be mentioned for example seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and parts of plants. Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion. Preferably “plant propagation material” is understood to denote seeds.

Pesticidal agents referred to herein using their common name are known, for example, from “The Pesticide Manual”, 15th Ed., British Crop Protection Council 2009.

The compounds of formula (I) may be used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation. To this end, they may be conveniently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions or suspensions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e.g. in polymeric substances. As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.

Suitable carriers and adjuvants, e.g., for agricultural use, can be solid or liquid and are substances useful in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO 97/33890.

The compounds of formula (I) are normally used in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be, e.g., fertilizers or micronutrient donors or other preparations, which influence the growth of plants. They can also be selective herbicides or non-selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.

The compounds of formula (I) may be used in the form of (fungicidal) compositions for controlling or protecting against phytopathogenic microorganisms, comprising as active ingredient at least one compound of formula (I) or of at least one preferred individual compound as above-defined, in free form or in agrochemically usable salt form, and at least one of the above-mentioned adjuvants.

The invention provides a composition, preferably a fungicidal composition, comprising at least one compound formula (I) an agriculturally acceptable carrier and optionally an adjuvant. An agricultural acceptable carrier is for example a carrier that is suitable for agricultural use. Agricultural carriers are well known in the art. Preferably, said composition may comprise at least one or more pesticidally active compounds, for example an additional fungicidal active ingredient in addition to the compound of formula (I).

The compound of formula (I) may be the sole active ingredient of a composition or it may be admixed with one or more additional active ingredients such as a pesticide, fungicide, synergist, herbicide or plant growth regulator where appropriate. An additional active ingredient may, in some cases, result in unexpected synergistic activities.

Examples of suitable additional active ingredients include the following acycloamino acid fungicides, aliphatic nitrogen fungicides, amide fungicides, anilide fungicides, antibiotic fungicides, aromatic fungicides, arsenical fungicides, aryl phenyl ketone fungicides, benzamide fungicides, benzanilide fungicides, benzimidazole fungicides, benzothiazole fungicides, botanical fungicides, bridged diphenyl fungicides, carbamate fungicides, carbanilate fungicides, conazole fungicides, copper fungicides, dicarboximide fungicides, dinitrophenol fungicides, dithiocarbamate fungicides, dithiolane fungicides, furamide fungicides, furanilide fungicides, hydrazide fungicides, imidazole fungicides, mercury fungicides, morpholine fungicides, organophosphorous fungicides, organotin fungicides, oxathiin fungicides, oxazole fungicides, phenylsulfamide fungicides, polysulfide fungicides, pyrazole fungicides, pyridine fungicides, pyrimidine fungicides, pyrrole fungicides, quaternary ammonium fungicides, quinoline fungicides, quinone fungicides, quinoxaline fungicides, strobilurin fungicides, sulfonanilide fungicides, thiadiazole fungicides, thiazole fungicides, thiazolidine fungicides, thiocarbamate fungicides, thiophene fungicides, triazine fungicides, triazole fungicides, triazolopyrimidine fungicides, urea fungicides, valinamide fungicides, and zinc fungicides.

Another aspect of invention is related to the use of a compound of formula (I) or of a preferred individual compound as above-defined, of a composition comprising at least one compound of formula (I) or at least one preferred individual compound as above-defined, or of a fungicidal or insecticidal mixture comprising at least one compound of formula (I) or at least one preferred individual compound as above-defined, in admixture with other fungicides or insecticides as described above, for controlling or preventing infestation of plants, e.g. useful plants such as crop plants, propagation material thereof, e.g. seeds, harvested crops, e.g., harvested food crops, or non-living materials by insects or by phytopathogenic microorganisms, preferably fungal organisms.

A further aspect of invention is related to a method of controlling or preventing an infestation of plants, e.g., useful plants such as crop plants, propagation material thereof, e.g. seeds, harvested crops, e.g. harvested food crops, or of non-living materials by insects or by phytopathogenic or spoilage microorganisms or organisms potentially harmful to man, especially fungal organisms, which comprises the application of a compound of formula (I) or of a preferred individual compound as above-defined as active ingredient to the plants, to parts of the plants or to the locus thereof, to the propagation material thereof, or to any part of the non-living materials.

Controlling or preventing means reducing infestation by insects or by phytopathogenic or spoilage microorganisms or organisms potentially harmful to man, especially fungal organisms, to such a level that an improvement is demonstrated.

A preferred method of controlling or preventing an infestation of crop plants by phytopathogenic microorganisms, especially fungal organisms, or insects which comprises the application of a compound of formula (I), or an agrochemical composition which contains at least one of said compounds, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen or insect. However, the compounds of formula (I) can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e.g., in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula (I) may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.

A formulation, e.g. a composition containing the compound of formula (I), and, if desired, a solid or liquid adjuvant or monomers for encapsulating the compound of formula (I), may be prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface active compounds (surfactants).

Advantageous rates of application are normally from 5 g to 2 kg of active ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kg a.i./ha, most preferably from 20 g to 600 g a.i./ha. When used as seed drenching agent, convenient dosages are from 10 mg to 1 g of active substance per kg of seeds.

When the combinations of the present invention are used for treating seed, rates of 0.001 to 50 g of a compound of formula (I) per kg of seed, preferably from 0.01 to 10 g per kg of seed are generally sufficient.

The compositions of the invention may be employed in any conventional form, for example in the form of a twin pack, a powder for dry seed treatment (DS), an emulsion for seed treatment (ES), a flowable concentrate for seed treatment (FS), a solution for seed treatment (LS), a water dispersible powder for seed treatment (WS), a capsule suspension for seed treatment (CF), a gel for seed treatment (GF), an emulsion concentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE), a capsule suspension (CS), a water dispersible granule (WG), an emulsifiable granule (EG), an emulsion, water in oil (EO), an emulsion, oil in water (EW), a micro-emulsion (ME), an oil dispersion (OD), an oil miscible flowable (OF), an oil miscible liquid (OL), a soluble concentrate (SL), an ultra-low volume suspension (SU), an ultra-low volume liquid (UL), a technical concentrate (TK), a dispersible concentrate (DC), a wettable powder (WP) or any technically feasible formulation in combination with agriculturally acceptable adjuvants.

Such compositions may be produced in conventional manner, e.g., by mixing the active ingredients with appropriate formulation inerts (diluents, solvents, fillers and optionally other formulating ingredients such as surfactants, biocides, anti-freeze, stickers, thickeners and compounds that provide adjuvancy effects). Also conventional slow release formulations may be employed where long lasting efficacy is intended. Particularly formulations to be applied in spraying forms, such as water dispersible concentrates (e.g. EC, SC, DC, OD, SE, EW, EO and the like), wettable powders and granules, may contain surfactants such as wetting and dispersing agents and other compounds that provide adjuvancy effects, e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, and ethoxylated alkylphenol and an ethoxylated fatty alcohol.

A seed dressing formulation is applied in a manner known per se to the seeds employing the combination of the invention and a diluent in suitable seed dressing formulation form, e.g., as an aqueous suspension or in a dry powder form having good adherence to the seeds. Such seed dressing formulations are known in the art. Seed dressing formulations may contain the single active ingredients or the combination of active ingredients in encapsulated form, e.g. as slow release capsules or microcapsules.

In general, the formulations include from 0.01 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and 10 to 99.99% solid or liquid formulation inerts and adjuvant(s), the active agent consisting of at least the compound of formula (I) together with component (B) and (C), and optionally other active agents, particularly microbiocides or conservatives or the like.
